Overview
The Allen-Bradley 2090-U3CBB-DM44 is a control interface breakout board kit designed for Ultra 3000 and Kinetix 2000 variable frequency drives. This drive-mounted assembly provides discrete wiring termination points for CN1 I/O connector signals, eliminating the need to solder or crimp individual control lines to the drive connector. The kit includes an integrated isolated 24V to 5.2V DC auxiliary power converter, enabling seamless integration into existing automation systems.
